MECHANISM FOR ASSEMBLING, FORMING, AND SETTING GARMENT-FASTENERS.

SPECIFICATION forming part of Letters Patent No. 661,297, dated November6, 1900.

Application led April 30, 1900- Serial No. 14,845. (No model.)

To all wtont it may con/cern:

Be it known that I, JAMES V. WASHBURNE, a citizen of the United States,residing at Waterbu ry, in the county of New Haven and State ofConnecticut, have invented an Improvenient in Tools for Mounting theMembers of Garment-Fasten ers, of which the following is aspecification.

My invention relates to tools or dies for mounting the members offasteners to gloves or garments.

ln my application, Serial No. 695,254, filed February 2, 1898, forimprovement in fasteners for gloves and garments, there are shown anddescribed dies or tools for mounting the members of fasteners to glovesor garments; but in said application a claim is made to the fastener andnot to the die or tool. The present application relates to the said dieor tool. These garment-fasteners usually consist of two parts ormembers, the one of cup shape and the other having a flange, the partwith the flange fitting down into thecup-shaped portion and carryingwith it the fabric of the garment which intervenes between the twoparts, the rim of the cup-shaped part being turned over the iiange ofthe other part. I employ a die having a recessed upper face adapted toreceive and hold the cup-shaped part or member of the fastener and asecond die above the VIii-st die provided with a tubular plunger. Thelatter die is made with an annular conical surface surrounding theplunger, and the plunger is adapted to hold the inner member of thefastening device, and the said plunger is spring-actuated and servesmainly to carry the inner member of the fastener, with the fabric, downinto the cupshaped portion, and the said plunger yields at this point,the connecting of the two parts being performed by the dies proper andby the annular conical surface surrounding the plunger bending inwardthe rim of the cup-shaped member and the fabric over the edge of theflange of the inner member.

In the drawings, Figure l is a vertical section of the parts of the diesfor holding the socket member of the fastener. Fig. 2 is a verticalsection of the same parts together with the parts of the fastener. Fig.3 is a vertical section of the dies and plunger for holding the studmember of the fastener.

Fig. 4: is a vertical section of the same dies with the parts of thefastener, and Fig. 5 is a vertical section of a complete die of approvedform and full size. In Figs. l and 3 the parts of the dies are separatedpreparatory to coming together, and Figs. l to at, inclusive, are ofexaggerated size for clearness.

The die a is recessed upon its upper face and adapted to receive themetal cup or head of the fastener. The outline of the recess agrees witht-he curved surface of the metal cup. The die c is centrally perforatedto receive the tubular plunger d. This plunger has a tubular end, and toit are connected spring-fingers 2, the base of the fingers being a blocklet into the solid portion of the plunger d, and the upper end of theplunger (l is tubular to receive the helical spring g.

The die c, Figs. 3 and 4, is similar to the die c, and both dies are intheir lower faces made with an inward conical surface 5. This die c iscentrally perforated to receive the plunger (I, which plunger isprovided with a tubular lower end and a tubular upper end for the springg.

The plunger d of the die c receives the socket member i of the fastener,the springfingers 2 passing Within the opening in the socket` member andserving to frictionally hold the socket member to the die d in a stateof suspension. The tubular plunger CZ is adapted to receive thespring-head of the stud member l of the fastener. In Figs. l and 3 thedies and the plungers are shown alone, while in Figs. 2 and 4 they areshown in relation to the parts of the fastener, the metal cups b beingin place upon the dies a, the socket member t' being held by the plungerd, and the stud memberl by the plunger d.

The fabric or material of the garment is shown at e, and the same passesover the rim of the metalcup and down within the cup below the flange ofthe socket member or the stud member, and the said material e intervenesbetween the two members, and when the dies are brought together in acloser relation than that shown in Figs. 2 and 4 the conical surface 5of the dies turns over the rim of the metal cup b down upon the flangeof the socket and stud member to hold the two parts of the fastenertogether. I have shown, as in my aforesaid application, a strip ofpaperf intervening between the material e of the garment and the metalcup b and over the edge of the rim of the said metal cup to preventcutting the fabric as the said rim is turned down upon the flange of theinner member.

The action of the dies in connecting the socket member and the metal cupor the stud member and the metal cup is identical. In the action ofthese dies and as the same descend with the stud and socket members,there is just sufficient force in the plungers d d to press the stud orsocket member and the fabric down into the metal cup, after which theplunger yields With the further downward movement of the die, theconical surface of Which turns the rim of the cup member over upon theflange of the inner member. The plungers hold the socket or stud memberwith sufflcient friction to support the said members or the fasteningdevice after the part-s are connected, but not sufficient to interferewith ready removal of the fastening device from the upper die.

In Fig. 5 I have shown the preferable form of complete die c', in whichthe plunger d/ is made tubular at the lower end and With a head at theupper end seating against a shoulder of the die-stem. The spring g isreceived in the opening in the die-stem and rests upon the upper surfaceof the head and is held in place by a screw-plug 7 in the upper end ofthe die-stem. The plunger d', Fig. 3, is shown as divided and as adaptedto receive a solid stud member of afastener, While the plu nger d', Fig.4, is shown as holding a split stud member. It is obvious that the diesmay be made to connect the parts of snap-fasteners, whether the same becircular or of other shape.

I claim as my invention- 1. A die having a recessed face formed toreceive the metal cup forming the head of the fastener, in combinationwith a die centrally perforated and having in the said perforation atubular spring-actuated plunger for holding the inner member of thefastener and an annular conoidal surface surrounding the plunger andadapted to act upon the rim of the cup-shaped head to turn the same overupon the edge of the inner member, substantially as set forth.

2. In a machine a die having a recessed upper face in combination withanother die over the same centrally perforated, a tubular plunger,spring-actuated and movable through the center of the upper die and theupper die having aconical surface surrounding the plunger, substantiallyas set forth.

3. In a machine a die having a recessed upper face in combination withanother die over the same centrally perforated, a tubular plunger,spring-actuated and movable through the center of the upper die and theupper die having a conical surface surrounding the plunger, andspring-fingers fixed to and located Within the tubular plunger,substantially as and for the purposes set forth.

Signed by me this 24th day of April, 1900.
